For the purpose of lattice optimization, eighteen individual quadrupole power supplies was installed in the SRRC storage ring in March 1997 to replace the three quadrupole family power supplies. In order to accomodate newly installed and already existed power supplies, the control interface of Taiwan Light Source (TLS) has been rejuvenated recently. The new control interface has improved drastically on control speed in comparison with the existed interface. Operation of the power supply system from device level to system level is reorganized to make control and access easier. This new control interface provides capability from complex operation such as lattice file loading, magnet degaussing, to file energy ramping scheme, etc. Performance of this power supply control interface including hardware components and software applications is presented.

In order to acquire necessary machine parameters information within reasonable time, supporting tools for automatic lattice parameters measurement is implemented in SRRC. Signal waveform detection, spectrum analysis, and associated control circuits were installed and tested, and the application programs were developed. These application program tool boxes can be activated with simple pop-up operation on workstation. Detailed functions and their status are presented in this report.

Aiming at the problems of high-altitude painting, an intelligent painting unmanned aerial vehicle (UAV) system, including hardware design and software implementation, has been developed. The hardware design of the system mainly includes three parts: drawer-type modular power supply, UAV intelligent painting control system, and high airflow ultra-high-speed motor drive system. The software realization mainly includes two parts: the control thread of the high-voltage main motor and the control thread of the solenoid valve for opening and closing. Besides, the target recognition processing scheme has been designed. To evaluate the accuracy and practicability of this technique, the UAV system has been applied for an intelligent painting experiment in an ultra-high voltage environment, successfully illustrating the feasibility of uninterrupted power supply intelligent painting by UAV.
